The Grain Weevil is a very small beetle, about 1/16th of an inch for the body length. The head is elongated into a snout. Grain Weevil larvae are small pale grubs without any legs.

Grain Weevils infest food products, especially dry organic materials found in the pantry. They commonly get into breakfast cereals. While they do not consume large amounts of the food material, their presence is enough to eliminate usage of the contaminated product.
